High power IR emitter, also known as infrared emitter, is a device that emits infrared radiation with high power. It is widely used in various fields such as industrial automation, medical equipment, security monitoring, and consumer electronics. In this article, we will introduce the industry of high power IR emitter, including its working principle, types, applications, and market trends.

Working Principle of High Power IR Emitter

The high power IR emitter is based on the principle of thermal radiation. When the temperature of an object reaches a certain level, it will emit infrared radiation. The high power IR emitter is made of a semiconductor material, which can convert electrical energy into heat energy, and then emit infrared radiation. The working principle can be described as follows: 1. The semiconductor material is excited by an external power supply, and the electrons in the material move to the conduction band, generating heat. 2. The heat is then converted into infrared radiation through the emission of photons. 3. The emitted infrared radiation is then focused and amplified by the optical system, achieving high power output.
